POWL change active query dynamically

Hello,

I have a WD abap application which contains two trays, one for selection fields and the second which contains POWL component.

I have more of ten queries on my POWL and by default I displayed this first.

My requirement is to change active query depending on action from my first tray ?

And then if it’s possible to select a specific line from the table result using index ?

Thanks for your help
